Travel through the ruined magic academy, the epic battlefield of blood and fire, and the doomsday scorched earth where demons wreak havoc.

When Zhang Peiran opened his eyes in the cycle of death, the bricks and stones of Hogwarts Castle were being corroded by the Dark Mark, the smoke of war in Middle-earth obscured the brilliance of the Silmarils, and the Eye of Sargeras could be seen on the broken coastline of Azeroth.

Voldemort's power was infused tenfold by the abyss. The Mordor orc army, accompanied by the fallen Maia, swept across the earth, and the Burning Legion's twisted fel warships obscured the entire starry sky.

There is no way to retreat, only hands holding the magic wand and rune sword, walking alone in every world where eternal night is approaching.

(Advance warning: This is a long and endless story with no female protagonist. It focuses on the magic system. The current planned routes are "Harry Potter World", "Lord of the Rings Middle-earth", and "Azeroth World of Warcraft".)

John Shafiq, son of a nun.

As a special wizard who can devour magic power.

From the day he gained power, he knew that the world was full of greed and malice towards him.

For him, Hogwarts was the only refuge in this world.

But the fledglings always have a time to spread their wings.

Even a dormant dragon will eventually rise from the abyss.

When that day comes, what will the appearance of the dragon leaping out of the deep pool be?

[Voldemort, why does your magic taste so bad? ]

PS: The protagonist is a human, not a dragon. Dragon is just a title.
